Predicting Products to Reactions

Predicting Products to Reactions. Create this chart. Synthesis Reactions. Example 1: Two elements  binary ionic compound 2Na (s) + Cl 2 (g)  2 NaCl (s) Example 2: Water and a small molecular gas  acid H 2 O (l) + SO 3 (g)  H 2 SO 4 (aq). Decomposition.

  1. Predicting Products to Reactions

  2. Create this chart

  3. Synthesis Reactions Example 1: Two elements  binary ionic compound 2Na (s) + Cl2 (g)  2 NaCl (s) Example 2: Water and a small molecular gas  acid H2O (l) + SO3 (g)  H2SO4 (aq)

  4. Decomposition Example 1: Binary ionic compound  pure elements 2 ZnO (s)  2 Zn (s) + O2 (g) Example 2: Water  hydrogen and oxygen gases 2 H2O (l)  2 H2 (g) + O2 (g) Example 3: Hydrogen peroxide  water and oxygen gas (needs a kick- light or MnO2) 2 H2O2 (aq)  2 H20 (l) + O2 (g)

  5. Single replacement Pure element and a ionic compound. Check the activity series of metals to see if the reaction will occur or check the order of halogens. I increasing activity F

  6. Examples Al(OH)3 (aq) + 3 Na (s)  3NaOH (aq) +Al (s) Al (OH)3 (aq) + Pb (s)  No reaction NaCl (aq) + Br2 (l)  No reaction 2 NaCl (aq) + F2 (g)  2NaF (aq) +Cl2 (g)

  7. Double displacement Two aqueous ionic compounds  2 new compounds in which one is a: *precipitate (insoluble compound) or *water or *molecule compound that would be a gas

  8. Examples CaBr2 (aq) + Na2CO3 (aq)  2 NaBr (aq) + CaCO3 (s) NaOH (aq) + HCl (aq)  HOH (l) + NaCl (aq) water NaClO3 (aq) + Li NO3 (aq)  No reaction because both products are soluble

  9. Combustion Hydrocarbon and oxygen gas water and carbon dioxide gas (complete combustion) 2 C2H6 (g) + 9 O2 (g)  6 H2O (g) + 4 CO2 (g)
